Embodiment
For making content of the present invention more clear understandable, below in conjunction with Figure of description, content of the present invention is described further.Certainly the present invention is not limited to this specific embodiment, and the known general replacement of those skilled in the art also is encompassed in protection scope of the present invention.
Please refer to Fig. 1, it shows the configuration diagram of the ultra-broadband emitter device of one embodiment of the invention.
The ultra-broadband emitter device comprises oscillator module 20, power amplifier driver module 30, data input module 40, switch control module 50.Wherein, oscillator module 20 couples power amplifier driver module 30.Oscillator module 20 produces the sine wave signal with certain operating frequency vibration, and exports this sine wave signal to power amplifier driver module 30.On the other hand, data input module 40 receives sine wave signals and is converted into the data-signal of extra small duty ratio short pulse from digital baseband 10.Switch control module 50 couples data input module 40 and power amplifier driver module 30, and switch control module 50 comes power ratio control amplifier driver module 30 intermittently to work in one-period according to the short pulse data-signal of this extra small duty ratio.Specifically, when switch control module 50 receives data-signal for " 1 ", switch control module Driver amplifier driver module work this moment, 30 equivalences of power amplifier driver module are in open mode, amplify the sine wave signal that transmits from oscillator module 20; The data message that receives when switch control module 50 is during for " 0 ", switch control module this moment Driver amplifier driver module 30 not, therefore whole power amplifier driver module 30 equivalences are in closed condition, can't amplify the sine wave signal that transmits from oscillator module 20, thereby only export a sine wave signal that is attenuated, perhaps under extreme case, do not have signal output.Thus, within a pulse period of the extra small duty ratio short pulse data-signal of data input module 40 outputs, power amplifier driver module 30 is under the control of switch control module 50, only the utmost point within this pulse period is worked in the short time and other times keep closing, intermittently modulate the high-frequency oscillation signal by oscillator module 20 outputs, thereby naturally produce the desired ultrashort pulse signal of ultra broadband, and the impedance of the outer transmitting antenna 60 of driving chip.Because working within the extremely short time and close in other times in the power amplifier driver module 30 periodic intermittent ground that switch control module 50 control power consumptions are larger, has saved the consumption of whole ultra-broadband emitter device, improved power efficiency.In addition, the supply voltage of whole transmitter installation also need not stop diverter switch, has avoided the energy dissipation that various capacitor charge and discharge operations cause in the switching over process.According to technical scheme of the present invention, realize by circuit, when emission equivalent is " 1 ", " 0 ", the average power consumption of uwb short pulse transmitter installation can be controlled in the 5mA.
Please refer to Fig. 2, in another embodiment of the present invention, the ultra-broadband emitter device also comprises frequency tuning module 70.Frequency tuning module 70 couples oscillator module 20, the operating frequency of the control bit control generator module 20 by the n position.In a preferred embodiment of the invention, control bit is 5, the operating frequency of frequency tuning module 70 control generator modules 20 changes between f1=3.6GHz, f2=4.1GHz, f3=4.6GHz, f4=5.1GHz, f5=5.6GHz, the effect of frequency tuning module 70 provides a plurality of operating frequencies and selects, increase the degree of freedom of whole ultra-broadband emitter device, satisfied the requirement of Communication Protocol for Wireless Sensor Network with the signal of guaranteeing the emission of ultra-broadband emitter device.
To sum up, ultra-broadband emitter device proposed by the invention, intermittently open and close in one-period by switch control module power ratio control amplifier driver module, further avoid the unnecessary energy consumption of transmitter installation when can effectively keep super low-power consumption, improve the operating rate of transmitter installation, in addition, the present invention has more increased the degree of freedom that ultra-broadband emitter device frequency is selected by the operating frequency of frequency tuning module controls oscillator module.
